IPC: C02F1/68
Filed: 1991-11-13
Abstract: PURPOSE:To obviate the generation of corrosion in pipings by blowing carbon dioxide into city water while injecting an aq. soln. or slurry of slaked lime to the city water to dilute the city water, thereby forming calcium hydrogencarbonate. CONSTITUTION:A Langelier index adjusting tank 5 is provided in a flow passage 4 for raw water and the aq. slaked lime soln. or slurry of the volume calculated from the empirically determined index of raw water and the desired Langelier index is supplied before the tank 5 from a producing tank 1. While the raw water is mixed with this soln. or slurry to dilute it, the raw water is sent to the adjusting tank 5 where the carbon dioxide of the prescribed amt. is blown under the regulation of a valve 6 by the pH signal of this liquid to form the calcium hydrogencarbonate. The Langelier index and pH of the city water are thereby adjusted to the desired values. As a result, there is no possibility of the corrosion of the device since there are no points to form the water indicating acidity according to the injection of the carbon dioxide. Since there is no need for treatment for preventing the corrosion, the red water is effectively prevented at a low cost.
